XVILLIAM lV. PIOKORN, OF GRAOEVILLE, FLORIDA.

SPECIFCATON forming part of Letters Patent No. 713,681, dated November 18, 1902.

Application filed September 27| 1901. Serial No. 76,812. {No modelfi T all Lw/tfmt t may concern/f Be it known that l, WILLIAM W. PICKORN, a citizen of the United States, residing at Graceville, in the county of Jackson, State of Florida, have invented certain new and useful Improvements in Seed Droppers and Distributors; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to implements for dropping seeds and distributing fertilizers; and it has for its object to provide a simple, cheap, and efcientimplement of this nature by means of which the seeds may be dropped at regular intervals and in proper quantity and from which the fertilizer will be distributed in proper quantity and without waste and in which the quantity of fertilizer distributed may be varied to suit different conditions.

Other objects and advantages of the invention will be understood from the following description.

In the drawings forming a portion of this specification, and in which like characters of reference indicate similar parts in the several views, Figure 1 is a side elevation showing the present invention, portions of hopper being broken away to better show the structure. Fig. 2 is a top plan view of the implement. Fig. 3 is a bottom plan view of the implement.

Referring now to the drawings, the present implement comprises a hopper A, which is divided by the vertical partition 5, extending longitudinally thereof to forni a compartment 6 and 7, in the bottoms of which are formed openings 8 and 9, respectively. The hopper is mounted upon the beams 10 and 11, which converge at the forward end of the hopper and beyond which convergent portions they lie in contact, as shown. On the under sides of the beams 10 and 11 are secured bearings 12 and 13, in which is mounted a shaft 14:, having cranks and 16 at its ends and which cranks are connected by pitmen 17 and 18 with the cranks 19 and 20 of a crank-shaft 21, mounted in bearings 22 on the beams 10 and l1 and within the lower portion of the hopper. The hopper has a false bottom 23, which is spaced upwardly from the beams 10 and 11 and in which the openings 8 and 9 are formed.

Upon the shaft 2l are fixed the two disks 24 and 25, the former having a plain periphery in which are formed pockets 26, while the disk is grooved circumferentially, the groove being arc shape in cross-section, and in the bottom of this groove are formed pockets 27.

Secured to the bottom 23 of the hopper is a spring-plate 28 between the disk 24 and the front of the hopper, it being understood that the disk 24E projects through the opening or slot 8 in the false bottom, and the plate 28, which is arcshaped,lies against the periphery of the disk and prevents crowding of the seeds in the section 6 of the hopper into the opening S at the front end thereof when the disk is rotated, it being understood that the section 6 of the hopper carries the seeds to be dropped.

In the section 7 of the hopper is placed the fertilizer, which as the disk 25 is rotated enters the .pockets 27 and is carried b v the pocket through the bottom of the hopper and then discharged upon the ground. To prevent wasting of the fertilizer between the disk and the rear end of the opening 9, a plate 29 is secured to the upper faceof the bottom 23 and has an arc-shaped lug 30 at its forward end, which engages in and completely fills' transversely the peripheral groove of the disk.

The use of the peripheral groove is to permit a continuous stream of fertilizer passing from the hopper when desired, and to regulate 0r cut off this stream a valve-plate 31 is provided and is slidably mounted in the guides 32, secured to the bottom 23. The rear end ofthe plate 31 is arc-shaped, so that it may fit in the peripheral groove of the disk 25, and the opposite end of the plate is upturned, as shown, and is provided witha threaded perforation, in which is engaged a thumb-screw 34E, which is engaged also with a threaded perforation in the plate 35, secured to the front face of the hopper, there being a perforation in the front wall of the hopper to receive the thumb-screw. By manipulation ofthe thumb screw the plate 3 1 may be moved toward and away from the disk to vary the feed of fertilizer through the bottom of the hopper, as will be understood.

To rotate the disks, a wheel 36 is fixed upon the shaft 14 midway of the ends thereof, so

IOO

that when the implement is moved along the shaft,and therewith the Wheel,will be rotated.

To the sides of the hoppel` are secured the handles 37, and to the under sides of the beams 10 and 1l are secured spring-plates 38 and 39 for the reception of earth-treating tools.

What is claimed is- An implement of the class described oomprising a hopper having an opening in its bottom, a disk rotatably mounted and projecting upwardly through the opening and into the hopper, said disk having a peripheral groove and spaced pockets in the bottom of the groove, a ,plate slidably mounted upon the bottom of the hopper and having one end formed to fit the groove of the disk, a xed WILLIAM W. PICKORN.
